Gut dysbiosis leads to LPS translocation, triggering intestinal and systemic inflammation via TLR4/MyD88/NF-κB signaling, promoting α-synuclein pathology. The peripheral gut barrier is the most viable intervention point, though CNS microglial TLR4 activation remains mechanistically tenuous. Best therapeutic approach: zonulin antagonists (larazotide) for gut barrier restoration combined with NLRP3 inflammasome inhibition rather than direct TLR4 blockade.

Hypothesis 1: Rutin suppresses tau aggregation by binding exposed beta-sheet nucleation motifs in MAPT repeat domains, especially PHF6-like steric zipper surfaces, and stabilizing a less aggregation-p...

Hypothesis 1 is plausible but vulnerable to the classic polyphenol problem: apparent anti-aggregation effects can reflect colloidal interference, fluorescence-quenching artifacts, or non-specific bind...
